Product Description:

The E33NLHB-LNW-NS-00 is a three-stack hybrid stepper motor manufactured by Kollmorgen for the E Hybrid Stepper Motors series. By advancing its rotor in 1.8-degree increments, the unit delivers open-loop or microstepped positioning for pick-and-place stations, indexing tables, and other motion stages. The SIGMAX construction concentrates magnetic flux to raise torque density, while the smooth shaft and standard mounting flange simplify direct coupling to gearheads or lead screws. This design allows the motor to provide controlled incremental motion without requiring position feedback in basic open-loop applications.

The NEMA 34 frame houses a rotor with 0.025 oz-in-s² of inertia. The motor produces a holding torque of 939 oz-in and can sustain an axial load of 180 lb. With a phase resistance of 0.55 Ω and a rated current of 5.4 A per phase, it is compatible with low-voltage microstep drives while limiting copper loss. Its 1.8-degree step angle provides 200 full steps per revolution, and the ±1.5% step accuracy supports repeatable positioning. Four parallel leads exit through a splash-proof conduit interface that mates with a 1/2-inch NPS threaded connector, helping prevent moisture from reaching the terminal board. The rotor inertia supports responsive acceleration in indexing and positioning applications.

An insulation system rated to Class B, 130 °C works with a thermal resistance of 2.0 °C/W to manage winding temperature during operation. An inductance of 5.7 mH affects current rise time and should be considered when selecting drive voltage and switching parameters. A withstand voltage of 340 VDC and an insulation resistance of 100 megohms support dielectric integrity between the windings and motor housing. The motor operates at ambient temperatures from -20 °C to +40 °C, making it suitable for equipment installed in locations without climate control. Its weight of 7.6 lb should be considered when selecting mounting hardware and determining the supported mass of a moving axis.
